摘要
分析3 MW风电主轴轴承热处理中存在的问题,计算轴承套圈淬火油槽的体积,重新设计淬火油槽结构,采用顶插式和侧插式组合搅拌器的淬火油槽,使3 MW风电主轴轴承在热处理二次淬火冷却过程中硬度达到标准要求。
The problems existing in heat treatment for main shaft bearings used in 3 MW wind turbines are analyzed. The volume of oil - quenching tank for the bearing rings is calculated, and the structure for oil - quenching tank is redesigned. The hardness of the bearing rings satisfies standard requirement for secondary quenching cooling process during heat treatment by adopting oil -quenching tank with top plug type and side plug type stirrers.
